Abstract

Introducing classical fields, we can completely transfer entanglement from discrete qubits to an entangled coherent state. The entanglement can also be retrieved from the continuous-variable state of the cavities to the atomic qubits. Via a postselection measurement, the atomic entangled state and entangled coherent state can be mutually transformed fully.
